Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626902, here are decompositions:

3 + 31626899 = 31626902
19 + 31626883 = 31626902
61 + 31626841 = 31626902
193 + 31626709 = 31626902
211 + 31626691 = 31626902
283 + 31626619 = 31626902
313 + 31626589 = 31626902
331 + 31626571 = 31626902

Showing the first eight; more decompositions exist.
